package man-db 2.6.1-2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

The package system is broken

Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f

The following packages have unmet dependencies:

krb5-multidev: Depends: libkrb5-3 (= 1.10+dfsg~beta1-2ubuntu0.1) but 1.10+dfsg~beta1-2 is installed
               Depends: libk5crypto3 (= 1.10+dfsg~beta1-2ubuntu0.1) but 1.10+dfsg~beta1-2ubuntu0.1 is installed
               Depends: libgssapi-krb5-2 (= 1.10+dfsg~beta1-2ubuntu0.1) but 1.10+dfsg~beta1-2 is installed
